My guess is super heated water due to daytime aeration. Hot water cant carry any oxygen.
New grass...any thoughts on fertilizer used on lawn? Some grass seed is pre-treated but that seems like a stretch.
I'm grasping at straws but since this is the 2nd time, might be time to think outside the box.
ETA, total poundage stocked?
Go out at dawn and see if any fish are gulping air at the surface.
bermuda grass seed that was coated, pelletized lime, high nitrogen fertilizer (don't remember the exact numbers) Covered seeds with hay.
Initial stocking in April was 500 BG, 50 SC, and 1000 FHM, lost around 200 BG, restocked 250.
BG are eating feed and spawning.
I think its a temp, dissolved oxygen problem. Where should water temps be and what is dangerous temp levels?
